ARTIFICIAL LIGHT AND HEAT CABINET.

SPECIFICATION forming part of Letters iatent No. 685,205, dated October22, 1901.

Application filed March 6, 1901.

T0 at whom it may concern:

Be it known that we, ERNST FEIX and AL FRED GOETHEL, citizens of theUnited States, and residents of Milwaukee, in the county of Milwaukeeand State of Wisconsin, have invented certain new and usefulImprovements in Artificial Light and Heat Cabinets 5 and we do herebydeclare that the following is a full, clear, and exact descriptionthereof.

Our invention has for its object to provide a simple and efiectiveapparatus for heating cabinets for medical treatment, and moreespecially for that class where artificial light is employed incombination with heat; and it consists in certain peculiarities ofconstruction and combination of parts to be fully set forth hereinafterwith reference to the accompanying drawings and subsequently claimed.

In the drawings, Figure 1 is a sectional view on line 1 1 of Fig. 2,showing our heating device applied to a cabinet in combination withelectric lights; and Fig. 2 is a section on line'2 2 of Fig. 1.

Referring by letter to the drawings, A A are the sides, and B thebottom, of a cabinet with a rear wall 0, said cabinet being providedwiththe usual doors, as indicated at D, Fig. 2, and is also providedwith a series of electric lamps E and lined with reflectingmirrors F'atvarious angles, which serve to intensify the light, the whole beingpractically air-tight when the patient is in position upon the seat G,the head remaining outside and projecting through an opening H in thetop of the cabinet, which is also provided with a vent I, that may beadjusted so as to regulate the circulation of air in the cabinet. Thebottom B of said cabinet has a central round opening J, under which isplaced a burner J of any ordinary construction, (gas or vapor,) inclosedin a metal duct K, open at one end, through which the cold air isconducted to the burner and when heated passes up through the opening J,abutting hood L, which deflects the air into chamberM and out through aseries of holes a a into Serial No, 50,069. (No model.)

a metallic false bottom N of a little less area than the cabinet-bottom,which said false bottom is also provided with a number of openings b b,through which the 'heat escapes to the cabinet. Said metal receptacle Nhas socured to its upper flat surface a non-conducting sheet of asbestos0', so as'to protect the feet of the patient from the intense heat whichwould otherwise radiate from the receptacle N.

It is obvious that with the several obstruc tions and receptacles forthe heat to pass through before it enters the cabinet (which it finallydoes near the outer edge of the same) it will be so distributed that thediscomfort of a concentrated heat, which is a great o'bjection to themethod of heating cabinets of ordinary use, is entirely overcome.

Having thus described our invention, what we claim as new, ahd desire tosecure by Letters Patent, is

In an artificial light and heat cabinet, a heater for the same locatedunder the bottom thereof, an airduct incasing said burner open at oneend, an opening in the bottom of said cabinet over said heater, a hoodsuspended above said opening, a rectangular chamber incasing the samehaving a series of orifices disposed at its sides, and a false bottominclosing the same with closed sides and ends of less area than thebottom of the cabinet, said sides and bottom being provided withopenings whereby hot air is discharged near the walls of the cabinet,and a covering of non-conducting material for the aforesaid falsebottom, substantially as set forth.

In testimony that we claim the foregoing we have hereunto set our hands,at Milwaukee, in the county of Milwaukee and State of Wisconsin, in thepresence of two witnesses.
